DESCRIPTION OF EMBODIMENTS

[0008] The technical solutions of the embodiments of the present disclosure will be clearly and completely described with reference to the drawings of the embodiments of the present disclosure. Obviously, the embodiments as described are just part of the embodiments of the present disclosure rather than all the embodiments. Based on the embodiments of the present disclosure, all the other embodiments obtained by a person skilled in the art without paying any creative effort fall within the protection scope of the present application.

[0009] An embodiment of the present disclosure provides a data interaction system which can implement the bi-directional data interaction between the remote controller and the AP. The structural block diagram of the data interaction system is shown in Fig. 1. The data interaction system comprises a remote controller and an access point AP. The remote controller is configured to send data in a certain format. The AP is configured to listen and receive data sent by the remote controller on a dedicated channel of the remote controller. The remote controller and the AP use identical communication parameters to perform a bi-directional data interaction. The AP returns response information to the remote controller after receiving the data sent by the remote controller. The response information may include Acknowledgement ACK or heartbeat information, wherein the ACK, that is, an acknowledgement character, is a kind of transport control character sent from a receiving station to a transmitting station during data communication, the ACK indicates that it is confirmed the data as sent having been received inerrably. The heartbeat message is a message sent from a transmitting station to a receiving station, and such message can make the receiving station determine whether and when the transmitting station has a fault or is terminated.

[0010] As shown in Fig. 2, the data interaction system further comprises a background server. The AP is further configured to forward the data sent by the remote controller to the background server. The background server is configured to process the data sent by the remote controller. The background server is further configured to feedback results of processing the data sent by the remote controller to the AP. The background server and the AP perform the bi-directional data interaction.

[0011] In implementation, the 2.4G wireless communication protocol can be used for the bi-directional data interaction between the remote controller and the AP, and a wired or wireless manner can be used for the bi-directional data interaction between the background server and the AP. The 2.4G communication channel can be used for the communication between the remote controller and the AP, with a default communication frequency point and a communication rate being consistent, and both of the remote controller and the AP use a same modulation mode. With the same communication parameter, the remote controller can transmit the information in a certain format to the AP which would continuously listen to any information sent by the remote controller on the dedicated channel of the remote control, and after receiving the information, the AP transmits the received information to the background server in the wired or wireless manner so as to make the background server perform a corresponding processing on the information. The use of a 2.4GHz technology is mainly due to the 2.4G technology being mature, and there is a standard communication frequency band (2.4GHz ISM) planed internationally. Based on the radio frequency characteristics of 2.4G, it is easy to implement a compact design (an antenna can be designed to be small and exquisite); meanwhile, it is easy to realize omni-directional communication ability without blind angle (the antenna can realize the omni-directional communication). Moreover, an uplink channel and a downlink channel of the 2.4GHz technology almost have the same capacity, and the uplink channel has a burst capability.

[0012] In implementation, in this embodiment, the data in the certain format comprises: a data packet type and remote control information carried by the data packet, wherein the remote control information may comprise one of or any combination of a remote controller user identifier, a remote controller identifier and a remote controller input information. The remote controller user identifier and the remote controller identifier can pre-set in the remote controller in advance. When the remote control information comprises the remote controller user identifier and the remote controller identifier, the remote controller provides the remote controller user identifier and the remote controller identifier to the AP, the AP transmits the remote controller user identifier and the remote controller identifier to the background server, and the background server can associate the remote controller user identifier with the remote controller identifier and perform the corresponding processing. When the remote control information comprises the remote controller user identifier and the remote controller input information, the remote controller input information herein represents a certain type of operation information, the background server can associate the remote controller user identifier with the remote controller input information, process the remote controller input information, and determine who is the remote controller user completing the operation corresponding to the remote controller input information.

[0013] In implementation, in this embodiment, the data in the certain format further comprises a check information, and the AP is also configured to perform an integrity check on the data in the certain format according to the check information.

[0014] In implementation, the AP is also configured to collect energy of the data packet uploaded by the remote controller, and transmit the energy of the data packet to the background server; the background server is also configured to analyze the energy of the data packet, and determine the position of the remote controller from the AP; wherein the data packet comprises the data in the certain format. For example, when the energy of the data packet is more than -40dBm, it is determined that the position of the remote controller from the AP is within 1 meter; when the energy of the data packet is between -60dBm and -40dBm, it is determined that the position of the remote controller from the AP is within 5 meters. In this embodiment, there may be a plurality of APs; the plurality of APs are also configured to collect energy of the data packet uploaded by the remote controller, and transmit the energy of the data packet to the background server; the background server is also configured to analyze the energy of the data packet uploaded by the remote controller which is collected by the plurality of APs, and determine the position of the remote controller; wherein the data packet comprises the data in the certain format.

[0015] In the following, the data interaction system of the embodiment of the present disclosure is applied to a practical scene and the function thereof is described in detail.
1. The data interaction system of the embodiment of the present disclosure is applied to the scene of personnel management of a retail mall and supermarket.
In the existing daily operation and management of the retail mall and supermarket, a shop assistant does manual operations in most cases. For example, as for the attendance management of the shop assistants, the common technology is to swipe a card, each shop assistant is equipped with an NFC contact card whose information is bound to the shop assistant information one to one, the attendance or departure of the shop assistant is confirmed by means of swiping the card. The card swiping machine in this method is fixed at a certain place, and the shop assistant must swipe the card at a designated place. The problems existing in the prior art can be solved by using the data interaction system of the embodiment of the present disclosure.
As shown in Fig. 3, when the shop assistant is equipped with a remote controller with a low cost, the basic information of the shop assistant, such as name, job number ID, and ID number of the remote controller itself, can be pre-set inside the remote controller. After the remote controller is pre-set with the relevant information, this remote controller can be linked to the AP. The remote controller provides the corresponding remote control information to the AP which can receive and forward the corresponding remote control information to the background server, and the background server would process the corresponding remote control information.
As for the personnel attendance, the data format between the remote controller and the AP is shown in Table 1.

Table 1

1B	1B	4B	4B	4B	2B
Packet type:	Packet length	Personnel name or ID	Remote controller	Reserved information	CRC check
attendance			ID

A packet head is used for indicating that it is the data packet of personnel attendance, this data packet is transmitted to the AP which forwards the data packet to the background server, and the background server associates the personnel name or ID with the remote controller ID, and perform a related processing. For example, it is possible to record the arrival time of the shop assistant, and to finally confirm that the shop assistant has arrived at the shop. Meanwhile, after the attendance information reported by the remote controller is acquired by the AP, the AP can calculate the position of the shop assistant from the AP by the energy information of the received data packet, and finally position the location of the shop assistant at the store, thereby providing information basis for the personnel scheduling and work arrangement of the store.
2. The data interaction system of the embodiment of the present disclosure is applied to the scene of item management of the retail mall and supermarket.

[0016] For example, the data interaction system of the embodiment of the present disclosure is applied to the scene of modifying a bulk price in a large shopping mall and supermarket. For a bulk area, generally, the price will be adjusted at any time based on the freshness of products. Based on similar reasons, the shop assistant often needs to manually input the bulk information and then print a shelf label of the bulk during the selling of the bulk, which wastes time and gives bad experience to the customer.

[0017] As shown in Fig. 4, the price of the bulk is modified by using the data interaction system of the embodiment of the present disclosure, which can speed up the adjustment process and provide convenient service for the stores. A communication initiator is the remote controller. Firstly, the shop assistant needs to input the price to be modified to the remote controller, and then acquire the goods information by using the remote controller to contact an electronic shelf label, and send the new price information and goods information to the AP after packaging the new price information and goods information. After receiving the new price information and goods information, the AP synchronizes the received new price information to the background server which substitutes the previous price information with the new price information, and transmits the new price information and the goods information via the AP to the electronic shelf label to be displayed, which is convenient for the store to manage the price and an amount of sales.

[0018] The data packet format of a changed price of the bulk sent from the remote controller to the AP is shown in Table 2.

Table 2

1B	1B	4B	4B	4B	2B
Packet type: price of bulk	Packet length	Shop assistant identity ID	Goods information	Price information	CRC check

[0019] The background server adjusts the price displayed on the electronic shelf label when receiving the information "packet type: price of bulk"; the "goods information" represents the type of merchandise whose price is modified by the shop assistant; and the "Price information" is the new price information input by the keys of the remote controller.

[0020] Based on the application scene of the retail mall and supermarket, due to the use characteristics of the retail mall and supermarket shop, the shop assistant often does the repetitive work, so a light, convenient and flexible application will lead to more efficient work. The remote controller in the system adopts a very light and convenient design, and supports one-key work mode at the same time. The workflow of this mode is as follows: firstly, the shop assistant sets his or her regular work contents into the remote control, and defines the corresponding keys, for example, key "1" represents attendance, key "2" represents modifying the price of bulk, so the shop assistant can pre-configure this setting into the remote controller, which can greatly lower the complexity of work in daily use, and can bring about very good user experience because the corresponding work can be completed only by pressing one key.

[0021] To sum up, the data interaction system in the embodiment of the present disclosure comprises the remote controller and the AP. The AP can listen on a dedicated channel of the remote controller and receive the data in a certain format sent by the remote controller; the remote controller and the AP use an identical communication parameter to perform the bi-directional data interaction, which implements the bi-directional data interaction between the remote controller and the AP.
